WOOD-WORKERS BENCH-VISE.

SPECIFICATION forming part of Letters Patent No. 317,760, dated May 12, 1885.

Application filed September 11, 1884. (No model.)

To all whom it may concern:

Be it known that we, GEO. W. GEIssEN- HAINER and OHARLns A. GEISSENHAINER,

'citizens of the United States, residing atPittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wood-W'orkers Bench-Vises, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to improvements in wood-workers bench-Vises; and it consists in the combination of the bench, which forms one jaw of the clamp, with the movable jaw, an arm secured thereto, asliding bar which passes through the side of the bench, and to which both the jaw and arm are attached, a guide for the sliding rod, and a screw for operating the movable jaw, all of which will be more fully described hereinafter.

Our object has been to furnish a vise that occupies less space than the kind now generally used, to make it portable, quicker in its action, equally effective, and less costly.

The accompanying drawings represent our invention, in which Figure 1 is a perspective of a vise which embodies our invention. Fig. 2 is a perspective of the guide for the sliding rod.

A represents the side of a work-bench, and

. B a movable jaw of a clamp or vise, the upper edge of which jaw is on a level with the top of the bench, and of sufficient length to procure a good grip,when closed, without inj uring the material placed between. The lower tapering end of the jaw B has a recess to admit e-dgewise a flat bar, 0, to which it is pivoted, so as to have a movement at its up per end in connection with the screw E. The bar 0 is of a length to extend through a guide in the side of the bench, so that by drawing it out or pushing it in the jaw is approached to the bench or removed away from it.

To the end of the bar 0, touching the outside of the jaw B, is an arm, D, rigidly attached, that, following the outside of the jaw upward, reaches to its middle and terminates in a head threaded for a screw, E, to enter. The screw E, when turned, pushes the jaw B toward the bench to close the c1amp,or draws it away from it to open it, and serves to firmly hold an object in the vise after the jaws have first been approached by hand as near as posthe guide that forms a fulcrum on which the bar is supported. The downward pressure slightly elevates the bar beyond its fulcrum, and causes a contact between the upper edge of the bar and the set-screw in the guide, thereby preventing the bar from sliding out of place after it has been adjusted, andthe greater the pressure the less the probabillty ofits sliding out of place.

We are aware that a vise having two jaws, and which is supported at its lower end upon or by an endwise-moving rod which passes through the side of the work-bench,is not new, and this we disclaim.

Having thus described our invention, we claim I 1. The combination of the bench, which forms one of the jaws of the vise, with the endwise-moving supporting ro'd O, which passes through the side of the bench, the jaw B,which is pivoted on the rod, the arm which is rigidly secured to the rod, and a screw which passes through the upper end of the arm, and which operates the pivotedjaw, substantially as shown.

2. The combination of the bench, which forms one jaw, the end wise-moving supporting-rod which passes through the guide and the side of the bench, the jaw B, pivoted upon the rod, the arm D, secured to the outer end of the rod, the screw E, for operating the jaw, and the guide secured to the side of the bench and provided with a set-screw, substantially as described.

In testimony whereof we affix oursignatures in presence of two witnesses.
